Unhooded Kenny is in this episode... there are several parts.. at about 1:45 when the boys are celebrating you can see both Tweek and unhooded Kenny (with his messy hair). Then again at whistling Willies (2:30), Tweek is #12 (you see his back) but in front, to the right of Kyle is Unhooded Kenny again... then a close ups at 2:37, 2:45, 3:00.

At 5:28 Kenny is on the left and Tweek on the right...

At 6:54 you can see unhooded Kenny on the field(on the right of Stan), but moments later, you see Tweek is in the Pit.

8:52 at whistling willlies again, both Tweek and unhooded Kenny...

So on and on...

They are easy to tell apart.. Kenny has darker, much less spikey hair (just messy and flat like), Tweek has lighter Spikier hair.

me=a hybrid of Tweek,Butters,Cartman,&Kyle!
